Why this sizing

This Extra Small Consul deployment supports up to 500 registered services using three m6i.large instances. Compute instances are the primary cost driver, accounting for over 90% of the $222 monthly total. A key consideration for this tier is the disabled high availability, meaning the control plane is not resilient to single server failures.
